Unit 8 Test- Human Impact on Water Systems

How does the construction of a dam in a watershed primarily affect the local groundwater levels?

• It increases groundwater levels by creating more surface water.

• It decreases groundwater levels by reducing the natural flow of water.

• It has no effect on groundwater levels.

• It increases groundwater levels by preventing evaporation.

Which of the following is a strategic plan to reduce the harmful impact of agriculture on surface water in a watershed?

• Using more chemical fertilizers to increase crop yield.

• Implementing buffer zones with vegetation to filter runoff.

• Increasing the number of irrigation channels.

• Building more roads for better access to fields.

What is one way human activities can positively influence ocean systems?

• Overfishing to control fish populations.

• Establishing marine protected areas to conserve biodiversity.

• Dumping waste to create artificial reefs.

• Increasing shipping routes for economic growth.

Evaluate the impact of oil spills on ocean systems and propose a strategic method to mitigate such impacts.

• Oil spills have no long-term effects; natural processes clean them up.

• Oil spills damage marine life; using bioremediation can help mitigate the impact.

• Oil spills only affect the surface; using dispersants is the best solution.

• Oil spills are beneficial as they create new habitats.

Which human activity is most likely to lead to the contamination of groundwater in a watershed?

• Planting trees along riverbanks.

• Overuse of pesticides in agriculture.

• Building parks and recreational areas.

• Installing solar panels on rooftops.

Analyze the effects of urban development on surface water quality in a watershed and suggest a strategic approach to minimize negative impacts.

• Urban development improves water quality; no action is needed.

• Urban development increases pollution; implementing green infrastructure can help.

• Urban development has no effect on water quality.

• Urban development decreases pollution; increasing construction is beneficial.

How does the increase in carbon emissions from human activities affect ocean systems?

• It leads to ocean acidification, harming marine life.

• It has no effect on ocean systems.

• It increases ocean salinity, benefiting marine life.

• It decreases ocean temperatures, stabilizing ecosystems.

Propose a strategic plan to reduce the impact of plastic pollution on ocean systems.

• Increase plastic production to meet demand.

• Implement recycling programs and reduce single-use plastics.

• Encourage the use of plastic bags for convenience.

• Dump plastics in designated ocean areas.

What is a direct consequence of deforestation in a watershed area?

• Increased biodiversity.

• Reduced soil erosion.

• Increased surface runoff and sedimentation.

• Improved water quality.

Evaluate the role of human activities in altering ocean currents and propose a strategic intervention to address this issue.

• Human activities have no effect on ocean currents.

• Human activities stabilize ocean currents; no intervention is needed.

• Human activities can alter currents; reducing greenhouse gas emissions can help.

• Human activities improve ocean currents; increasing industrial activities is beneficial.
